The acute effect of ischemic preconditioning (IPC) on the maximal performance in 100-m freestyle event was studied recreational swimmers. 15 swimmers (21.0±3.2 years) participated a random crossover model 3 different days (control [CON], IPC or SHAM), separated by 3–5 days. consisted 4 cycles 5-min occlusion (220 mmHg)/5-min reperfusion each arm, and SHAM protocol similar to but with only 20 mmHg during phase. subjects were informed that both maneuvers (IPC SHAM) would improve their...

This study evaluated the effect of ischemic preconditioning (IPC) on resistance exercise performance in lower limbs. Thirteen men participated a randomized crossover design that involved 3 separate sessions (IPC, PLACEBO, and control). A 12-repetition maximum (12RM) load for leg extension was assessed through test retest before first experimental session. The IPC session consisted 4 cycles 5 minutes occlusion at 220 mm Hg pressure alternated with reperfusion 0 total 40 minutes. PLACEBO cuff...

This study evaluated the effect of ischemic preconditioning (IPC) on resistance exercise performance in upper limbs. After 12-RM load determination, 21 men attended 4 trials separated by 3 days a randomized crossover design: IPC (4×5-min occlusion 220 mmHg/reperfusion 0 mmHg) arms and thighs, SHAM (equal to protocol but "occlusion" at 20 thighs. 8 min following respective interventions, subjects performed one set elbow flexion with until concentric failure. The number repetitions increased...

Compression garments, utilized in sports and exercise for performance enhancement recovery, lack sufficient well-controlled studies to overcome any potential placebo effect. Therefore, we tested whether wearing compressive pantyhose (CP) during the Ballet-specific aerobic fitness test (BAFT) would influence performance, physiological, perceptual indicators. Additionally, this pilot study feasibility of research procedures informed adjustments main study. Nine young classical ballerinas...

We thank Schumann et al. (Schumann, Feuerbacher 2024) for their engagement and thoughtful comments on our article (Ide, Silvatti 2023), the overarching use of terminology in sports science. Academic debate is critical advancing field, we welcome opportunity to clarify expand arguments. While comment offers a perspective practical use, maintain that application “explosive” scientific literature may be both unnecessary potentially misleading.

Heart rate variability (HRV) analysis consists in a well-established tool for the assessment of cardiac autonomic control, both humans and animal models. Conventional methods HRV rats rely on conscious state electrocardiogram (ECG) recording based prior invasive surgical procedures electrodes/transmitters implants. The aim present study was to test noninvasive inexpensive method ECG rats, assessing its feasibility analysis. A custom-made elastic cotton jacket developed fit rat's mean...

We determined the optimal load for peak power output (PPO) during bench press throw (BPT) in Brazilian Jiu-Jitsu (BJJ) athletes and compared PPO maximal strength between advanced (AD) nonadvanced (NA) athletes. Twenty-eight BJJ (24.8 ± 5.7 years) performed BPT at loads of 30, 40, 50, 60% their 1 repetition maximum (RM) a randomized order (5-minute rest BPTs). The was by measuring barbell displacement an accelerometer (Myotest). absolute (F = 7.25; p < 0.001; effect size [ES] 0.21) relative...

Correction to: Acute Effect of Ischemic Preconditioning is Detrimental to Anaerobic Performance in CyclistsInt J Sports Med 2014; 35(11): 912-915DOI: 10.1055/s-0034-1372628

This study evaluated the acute effect of ischemic preconditioning (IPC) on a high-intensity intermittent exercise performance and physiological indicators in amateur soccer players. Thirteen players (21.5 ± 2 yrs) attended three trials separated by 3–5 days counterbalanced randomized cross-over design: IPC (4 × 5-min occlusion 220 mmHg/reperfusion 0 mmHg) each thigh; SHAM (similar to protocol but “occlusion” at 20 control (seated during same time IPC). After 6-min trial (IPC, or control),...

We verified the acute effect of ischemic preconditioning (IPC) in cyclists before high-intensity and short-duration activity. 15 amateur participated a random crossover model on 2 different days [IPC or CONTROL (CON)]. Ischemic consisted 4 cycles 5 min occlusion/5 reperfusion each thigh. After IPC CON, volunteers performed series Wingate tests to evaluate anaerobic performance (maximal [Pmax] medium [Pmed] power output, total power, fatigue index). Blood lactate concentrations were assessed...

Abstract The aim of this study was to investigate the neuromuscular performance responses following successive Brazilian Jiu-Jitsu (BJJ) fights. Twenty-three BJJ athletes (age: 26.3 ± 6.3 years; body mass: 79.4 9.7 kg; height: 1.80 0.1 m) undertook 3 simulated fights (10 min duration each separated by 15 rest). Neuromuscular measured bench press throw (BPT) and vertical counter movement jump (VCMJ) tests, assessed before 1st fight (Pre) after last one (Post). Blood lactate (LA) at Pre, 1...

Brief moments of blood flow occlusion followed by reperfusion may promote enhancements in exercise performance. Thus, this study assessed the 24-h effect post-exercise ischemic conditioning (PEIC) on performance and physiological variables trained cyclists. In a randomized, single-blind study, 28 cyclists (27.1 ± 1.4 years) performed maximal incremental cycling test (MICT). The outcome measures were creatine kinase (CK), muscle soreness perceived recovery status, heart rate, exertion power...

We investigated the match demands (distances covered and acute physiological responses) of amputee soccer its impact on muscular endurance power. Measures such as heart rate, blood lactate concentration, subjective rating perceived exertion, time-motion characteristics were recorded in 16 Brazilian players during matches. Before after matches, completed a battery tests: push-ups, countermovement vertical jump performance, medicine ball throwing. Small differences found between first second...

For the ischemic preconditioning (IPC) intervention, accuracy of protocol is paramount for mediating its possible ergogenic effects. However, lack standardization and widespread use arbitrary cuff pressures (ranging from 130 to &gt;300 mmHg) have been predominantly observed, potentially affecting results compromising reproducibility findings. Thus, purpose this study was determine an appropriate pressure during IPC. Seventeen healthy male participants were enrolled in study. Anthropometric...

After menopause, rapid bone mass loss occurs in response to hypoestrogenism. Several studies suggest that muscle and mineral density (BMD) are positively associated postmenopausal women. Therefore, it may be assumed low appendicular (aMM) can increase BMD a short period of time. The purpose this study was assess relationship aMM with femoral neck Prospective, controlled clinical Trial including 64 women aged 45-70 years, who had not their last menstruation for at least one year. Subjects...

This study quantified the degree of game-induced muscular fatigue in amputee soccer players.Thirty-three male players performed tests (Push Up Test [PUT], Countermovement Jump [CMJ] and medicine-ball throw [MBT]) before after a competitive match. Five served as control group. The rating perceived exertion was recorded each battery.Control group demonstrated no differences between two testing batteries (P>0.05, effect size [ES]: 0.1-0.4). However, match illustrated markedly lower performances...
